LIVE IN DOVER NOW, WITH THE FINAL THOUGHTS FROM EACH SIDE. JEN? YOU KNOW, EACH SIDE TOOK OVER TWO HOURS TO GO OVER THE FINER POINTS OF THIS CASE ABOUT WHO WAS ULTIMATELY IN CONTROL IN THAT RELATIONSHIP BETWEEN MAZZAGLIA AND KAT MCDONOUGH, AND WHOSE VERSION OF HOW LIZZI MARRIOTT DIED IS TO BE BELIEVED. THEN ULTIMATELY WHO SHOULD TAKE RESPONSIBILITY FOR HER DEATH. SETH MAZZAGLIA'S DEFENSE TEAM CLAIMS THE STORY KAT MCDONOUGH GAVE THE JURY, THAT HE STRANGLED AND RAPED LIZZI MARRIOTT, IS BUILT ON MISREPRESENTATION THAT KAT NEEDS THEM TO BELIEVE TO PROTECT HERSELF, ABOUT HER NOT WANTING WOMEN AND NOT EVER TAKING A SEXUAL DOMINANT ROLE. I'M SORRY, TYING HIM DOWN TO THE BED, LEAVING BITE MARKS, SCRATCH MARKS, CLAW MARKS, BRUISES, IF THAT AIN'T COME I NATION -- DOMINATION, WHAT IS? IT'S A LOT OF . HE TRIED TO LIE TO THE GRAND JURY, TRIED TO LIE TO YOU. TALKING ABOUT THE DARK CHARACTERS, THAT SETH WAS PLAYING ALONG, REACHESES IN WHICH HE SEEMED SWEET AND CARING. IS THIS THE PERSON WHO IS TAKING ON THIS STUFF SO SERIOUSLY? THAT IT IMPACTED THE EVENTS OF THE NIGHT. THAT IT WOULD CHANGE FROM A PLEASANT EVENING TO A HOMICIDAL RAGE. DO YOU HAVE DOUBTS ABOUT THAT? BUT THE STATE SAYS MCDONOUGH HAD EVERY REASON TO FINALLY TELL THE TRUTH AND THAT EVIDENCE SUPPORTS IT, AND PROVES MAZZAGLIA IS GUILTY. THERE WAS NO ACCIDENT. USE YOUR COMMON SENSE. A DEFENDANT WHO MAKES PLANS TO KILL EYEWITNESSES TO LIZZI'S BODY BEING IN HIS APARTMENT WAS NOT INVOLVED IN AN ACCIDENT. THE PROSECUTION CALL WHAT MAZZAGLIA DID CALCULATED FIRST DEGREE MURDER, REFERENCING A PICTURE OF LIZZI MARRIOTT TO UNDERSCORE WHAT IT CONTEND THE DEFENDANT DID TO HER. THAT SHE WAS PULLED UNSUSPECTINGLY INTO A BDSM PLAN, TURNED HIM DOWN, AND DIED FOR HIM. SEND HIM THE MESSAGE THAT YOU'VE SEEN THROUGH THE LIES, THE COVERUPS, THE MANIPULATION, SEND HIM THE MESSAGE YOU'VE SEEN THROUGH IT ALL AND KNOW THE TRUTH ABOUT HIM. THAT HE IS A COLD BLOODED KILLER. THE JUDGE DIDN'T FEEL THERE WAS ENOUGH TIME TO PLAIN THE RULES OF LAW TO THE JURY, SO HE'S GOING TO DO THAT IN THE MORNING. THEY'LL BEGIN DELIBERATIONS LIKELY AFTERNOON. JURORS WILL BE CONSIDERING FIVE CHARGES AGAINST MAZZAGLIA. THERE ARE TWO COUNTS OF FIRST DEGREE MURDER. THE FIRST ALLEGES THAT HE STRANGLED LIZZI MARRIOTT ON PURPOSE. AND THE SECOND SAYS HE DID SO WHILE ALSO SEXUALLY ASSAULTING HER. JURORS CAN ALSO CONSIDER A LESSER CHARGE OF SECOND DEGREE MURDER THAT HE RECKLESSLY CAUSED THE DEATH OF LIZZI MARRIOTT. OTHER CHARGES INCLUDE WITNESS TAMPERING FOR ALLEGED CONVERSATIONS WITH KAT MCDONOUGH ON THER TO THEY WOULD GIVE POLICE ABOUT THE CRIME. AND FALSIFYING EVIDENCE FOR ALLEGEDLY DUMPING MARRIOTT'S BODY AND THROWING AWAY ITEMS CONNECTED TO HER DEATH.
